STRFMON(3) NetBSD Library Functions Manual STRFMON(3)
NAMEstrfmon -- convert monetary value to string
LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS#include <monetary.h>ssize_tstrfmon(char * restrict s, size_t maxsize, const char * restrict format,
...);
DESCRIPTION
The strfmon() function places characters into the array pointed to by s
as controlled by the string pointed to by format. No more than maxsize
bytes are placed into the array.
The format string is composed of zero or more directives: ordinary char-
acters (not %), which are copied unchanged to the output stream; and con-
version specifications, each of which results in fetching zero or more
subsequent arguments. Each conversion specification is introduced by the
% character. After the %, the following appear in sequence:
· Zero or more of the following flags:
=f A `=' character followed by another character f which is used as
the numeric fill character.
^ Do not use grouping characters, regardless of the current locale
default.
+ Represent positive values by prefixing them with a positive
sign, and negative values by prefixing them with a negative
sign. This is the default.
( Enclose negative values in parentheses.
! Do not include a currency symbol in the output.
- Left justify the result. Only valid when a field width is spec-
ified.
· An optional minimum field width as a decimal number. By default,
there is no minimum width.
· A `#' sign followed by a decimal number specifying the maximum
expected number of digits after the radix character.
· A `.' character followed by a decimal number specifying the number of
digits after the radix character.
· One of the following conversion specifiers:
i The double argument is formatted as an international monetary
amount.
n The double argument is formatted as a national monetary amount.
% A `%' character is written.
RETURN VALUES
If the total number of resulting bytes including the terminating NULL
byte is not more than maxsize, strfmon() returns the number of bytes
placed into the array pointed to by s, not including the terminating NULL
byte. Otherwise, -1 is returned, the contents of the array are indeter-
minate, and errno is set to indicate the error.
ERRORS
The strfmon() function will fail if:
[E2BIG] Conversion stopped due to lack of space in the buffer.
[EINVAL] The format string is invalid.
[ENOMEM] Not enough memory for temporary buffers.
